What is the theme to the Cosmos television series called?

An extensive and varied ammount of music was used in the original broadcast including works by Edgar Froese (Tangerine Dream), Brian Eno, Pink Floyd and Jean Michel-Jarre. However, it is the 3rd movement of Heaven and Hell by Vangelis which is most recognised. It is this, which was used as the main theme.

Taken from the album of the same name, the 3rd movement is often called Theme from Cosmos on compilation albums (for example The Gift) as it was on the 7" single release.

Confusingly Vangelis also wrote a new track for "the special edition" which is also called Theme from Cosmos, but this has never been released.

Here then is a full listing of all the Vangelis music used in the original series.
